There are people whom psychologists call “extreme dreaders”—people who have a tendency to live in a state of heightened anxiety. Then there are people like Shacham. What makes him able to negotiate extreme fear so well? How does he navigate through the fog of deliberation without a map? When I ask him this question, he says it’s not that he doesn’t feel fear; he does, every time. But a calmness resides just adjacent to the fear. “You have to be very cold-blooded,” he says. But what makes someone “cold-blooded”? Is it genetics? Experience? A chemical imbalance? What makes the difference?
